Abstract: ABSTRACT OF THE DISCLOSURE        Process for the regeneration of synchronizing signals used for writing and/or reading recorded digital data or for recording on an optical data carrier, wherein the synchroniz-ing signals are regenerated in phase by determining the phase shift of the centre of specific pulses with respect to a clock signal. According to a preferred variant, the specific data and the useful information data are coded by a N.R.Z-type code, the specific data being associated with pulse durations not used in the N.R.Z. code for recording information data. The specific data can be recorded in time multiplexing with digital information data or, according to a preferred variant, in the form of flags at regularly spaced locations on the tracks which define between them zones intended for the recording of data blocks. The recording of these flags can take place prior to any recording of digital information data in preetched form. The synchronizing signals regenerated on the basis of the reading of these flags can then also be used for writing during the information data recording phases.

Abstract: 1270.001              POSITIVE CLUTCH DIFFERENTIAL     ABSTRACT OF DISCLOSURE   A differential assembly of the automotive vehicle type, for rotating axially aligned drive axles, having a rotatable driving casing which distributes the power to the inner end portions of the axles. A center ring member, having opposite wedge-like, face tooth formations, is secured within the casing for meshing with and driving corresponding tooth formations on a pair of pressure rings between which the center ring member is positioned. Each pressure ring is connected to one of the axles through a clutch. The pressure rings are movable towards and away from the center ring for respectively disengaging and engaging their clutches. A splined stop ring meshes with corresponding internal splines formed on each of the pressure rings for limiting each pressure ring's rotational movement relative to the center ring for holding the meshed center ring teeth and the teeth of either pressure ring apart when that pressure ring's rotational speed exceeds the rotational speed of the center ring and casing. During such speed conditions, the respective pressure ring can move towards the center ring so as to disengage its clutch and permit its axle to free wheel while the opposite axle is still driven by the rotating casing.

As the upper assembly is tilted, it pivots about this line and therefore remains substantially in balance for all angles of tilt.  To provide  static  rest pressure  to prevent  unwanted tilting movement and also to minimise backlash, the pinions in each pair are coupled together through an idler pinion.
